Four In A Row
Get four or more in a line on a square grid with gravity: stones fall down a column until they rest.
Inventors: Ned Strongin, Howard Wexler
Rules
Related commercial game: BoardGameGeek: Connect Four. Overlines count as wins (four or more).
Variants
10×10 board
Larger grid (standard-10).
Swap-1st / Swap-2 / Swap-5 openings
Pie-style colour swaps after the first stone, after a three-stone offer, or after each of the first five stones.
Edge-grow-4
You may also grow inward from the other three edges: place in the first empty cell from top, left, or right, not only from the bottom.
Interior-gravity-4
You may click any empty cell; the stone then slides toward the nearest edge (or along the diagonal toward a corner when equidistant) until it sits against a stone or the rim.
Clear
If an entire edge row or column is full, it is cleared and remaining stones shift that way — unless a four-in-a-row already exists, which wins first. With four-edge placement, any full edge line can clear.
